SPECIFICATION forming as of Letters Patent No. 685,127, dated October22, mm.

'Applioation filed ZI'uly 3,1901. Serial No. 66,992. (No model.)

To all within itmity n'berh: p

, Be it known that 1,11ARRY R. GEER, a citizen of the United States,residing at Elyria, in the county of-Lorain and State of Ohio, haveinvented or discovered certain new and useful Improvements inCooling-Beds for Plates or Bars, of which improvements the following isa specification;

The invention described herein relates to certain improvements incooling-beds and mechanism for transferring metal bars step by stepalong such'bed.

It is an object of the invention to provide for the step-by-stepshifting of one or more of the bars along the bed without effecting anychange in the position of the bar thereon-i. 6., Without causing the barto fall over or to roll during the shifting operation.

The invention is hereinafter more fully described and claimed.

In the accompanying drawings, forming a part of this specification,Figure 1 is a top plan view of my improved cooling-bed. Fig. 2 is a sideelevation of the same. Fig. 3 is a sectional elevation on a planeindicated by the line III III, Fig. 1. Figs. 4, 5, and 6 are transversesections on planes indicated, respectively, by the line IV IV, Fig. 2,and lines V V and VI VI, Fig. 3. Fig. 7 is a detail view, on an enlargedscale, of a portion of one of the moving skids.

In the practice of my invention the bed consists of a series ofstationary plates or skids 1, which for some purposes may be inclined,as shown, and are supported on suitable fo u ndation plates or beds 2and a series of compound movable skids arranged parallel andintermediate of the stationary skids or plates.

These compound skids consist of a plate or bar 4, movably supported uponrollers 3, two or more in number, side plates 5, and a supporting-plate6, secured between the side plates, which extend 011 both sides of themain plate 4. The stationary skids or plates 1 are provided at the endsadjacent to the feed-table of the rolling-mill, such table beingindicated at a and having an incline 19, down which the plates or barsto be cooled are fed to the cooling-table, with a fixed stop-shoulder 7.A series of two or more dogs 8 are pivotally mounted at intervals alongthe stationary skids or plates and have their lower ends weighted, so asto normally hang in a vertical position, with their upper ends above theupper edges of the skids or plates. These dogs are held as againstmovement in onedirection by means of stops 9, against which the lowerends of the dogs will bear, while their upper ends are presseddownwardly or to the right by the weight of the plates or bars restingon the skids. The movable skids or plates are provided with stationaryfingers or projections 10 at their lower ends and with a series ofpivotally-mounted dogs 11 arranged along their length a distance apartapproximately equal to the spacing of the dogs 8. These dogs 11 havetheir lower ends Weighted, so that they will automatically return tonormal position when shifted therefrom, as hereinafter described, andare held as against rotation in one direction by means of stops 12. Thecarrying members 4 of the movable skids are connected by rods 13 tocrank-arms let on the power-shaft 15, whereby the movable skids arereciprocated.

In normal position the movable skids are supported so that the fixedprojections 10 and the dogs 11 are in line or a little below thecorresponding parts of the stationary skids, so that as the plates orbars are fed down the apron b they will drop onto the skids and slidedown against the fixed stpps l0 and 7. As soon as a sufficient number ofplates or bars have accumulated above the fixed stops the shaft 15 isrotated, thereby causing the movable skids tomove upwardly. At the timeor a. little previous to the contact of the fixed fingers 10 with theplates or bars the movable skids are raised by the riding up on theroll-' 'ers 3 of shoulders or lateral enlargements 16 of the members 4of the movable skids, so that the upper edges of the bearing members 6of the movable skid will rise above the edge of the stationary skids,carrying the plates or bars out of contact with the latter. By thecontinued upper movement of the movable skids the plates or bars arecarried beyond the dogs 8, which will turn down to permit the pasy sageof the plates or bars until the fixed StEP 7 is passed a little beyondthe lower dog 8, carrying with it the plates or bars, so as to permitthe pivoted dogs 8 resuming their normal positions. The movable skidsthen begin their return movement in the same plane,

carrying with them the plates or bars until they rest against the dogs8. At this time the bearing-pieces 6 of the movable skids are droppeddown, so that the plates or bars will rest upon the stationary skids,and the movable skid will continue its downward movement without contactof any part thereof with the plates or bars. This dropping movement ofthe bearing-pieces of the movable skids can be eifected in any suitablemanner-such, for example, as that shown in Figs. 3, 5, 6, and 7. Astherein shown, the upper surfaces of the carrying portions 4 of themovable skid and the lower edges of the bearing-pieces 6 have inclinedrecessed portions 17, between which are interposed rollers 18. Theseparts are so proportioned and constructed that when the plates or barsstrike against the dogs 8, thereby checking the movement of the portions6 of the movable skids, the main portion 4: thereof may continue on, sothat the roller 18 will enter the deepest portions of the inclines orrecesses of the portions t and 6 of the skid, and thereby permit thebearing portion 6 to drop down below the level of the upper edges of theskid 1. As soon as the main portion of the movable skids reaches thelower limit of its movement and the shoulders or enlargements 16 passofi of the rollers 3 the portions 6 will slide down automatically andresume normal position, being slightly raised by this downward movementuntil their upper edges come into alinement or approximately intoalinement with the upper edges of the stationary skids.

I claim herein as my invention- 1. A cooling-bed for plates or bars,having in combination a series of stationary skids, one or more dogspivotally mounted 011 said skids, a series of two or more movable skids,means for raising the movable skids at or near the beginning of theirmovement in one direction and means for lowering the movable skids at ornear the beginning of the return movement of the skids, substantially asset forth.

2. A cooling-bed for plates or bars, having in combination, a series ofstationary skids, one or more holding-dogs pivotally mounted on theskids, a series of carrying-plates mov ably mounted intermediate of thestationary skids, a series of bearing plates movably mounted on thecarrying-plates, means for reciprocating the saidplates,pivotally-mounted dogs carried by said plates, means for raisingand lowering said plates at or near the beginning of the shiftingmovement, and means for lowering and raising the bearingplates at thebeginning and end of the return movement of said plates, substantiallyas set forth.

3. A cooling-bed for plates or bars, having in combination, a series ofstationary skids,

one or more dogs pivotally mounted on said skids, a series ofcarrying-plates movably mounted intermediate of the stationary skids, aseries of bearing-plates movably mounted on the carrying-plates, theadjacent edges of said carrying and bearing plates being provided withinclines or recesses, rollers interposed between said inclined orrecessed portions, pivotally-mounted dogs carried by the bearing-plates,means for reciprocating the carrying-plates, and means for raising andlowering said plates at the beginning and end of their movements,substantially as set forth. In testimony whereof I have hereunto set myhand.
